Agua Fresca

This tasty and refreshing drink is made with dried hibiscus flowers, also known as roselle or Jamaican sorrel. Essentially, it’s an herbal iced tea, but perhaps the most beautiful one you’ve ever had, with a brilliant magenta color extracted from the flowers. I like to soak the flowers overnight, as is traditional in my family, because I feel this extracts more of the subtle, tart, berrylike flavor. Once you’re done, instead of discarding the hibiscus flowers, save them to snack on. They’ll be a little sweet, and I think they’re delicious. Just be sure to keep them refrigerated.

When I was growing up, my sister and I often went to the market with my mom. There was a great juice stand where they made all kinds of aguas frescas and smoothies. This was my sister’s favorite one. It’s incredibly refreshing, and really good for you, too. The type of alfalfa used for these drinks resembles wheat grass and is grown abundantly in Mexico; you may be able to find alfalfa at nurseries and farmers’ markets. Pineapple is commonly mixed with a variety of green herbs. In the Yucatan, for example, it’s often blended with chaya. If you can’t find alfalfa or chaya, use a couple tablespoons of fresh mint.

This quick and refreshing drink is great on its own, but it’s also a good base for other beverages. Try stirring in some chopped fresh mint, raspberries, honeydew, or pineapple, or a combination. I’m not sure how it works, but rubbing the end really does help remove bitterness from standard cucumbers; the trick doesn’t apply to English or Persian cucumbers.

When I first moved to the States, I often had major cravings for this beverage. In Mexico, chia seeds are sold in most markets and spice shops, but I couldn’t find them anywhere in the States, and when I tried to explain what they were, people looked at me like I was crazy. Then, late one night when I was watching TV, I saw this thing called the Chia Pet. I had found my seeds! Chia seeds look like poppy seeds, but when soaked in liquid for a while, they bloom and develop an awesome gummy texture. This limeade is made using the whole lime, which gives it a slight bitterness, but trust me: it’s so good you won’t want to make it any other way.

Look for dried hibiscus flowers at specialty food shops and Latin markets.

Luis Miguel López Alanís of Morelia, Mexico, writes: "Although I grew up in Mexico, it was in Chicago of all places that I learned to cook Mexican food. During the two years I lived there, I missed my country's food so much that I wrote to my mother in Zitácuaro and asked her to send me recipes so I could cook for myself. "Now I work as a tour guide in Michoacán, my home state, where I lead tours on Morelia's colonial history and architecture, and show tourists the Paricutín Volcano and monarch butterfly sanctuaries. And sometimes I do restaurant and market tours. Whenever business slows down, I enjoy cooking for my family.

Agua Fresca de Jamaica Mexico has a wonderful variety of sweetened flavored waters known as aguas frescas, which are sold at street stands and marketplaces throughout the country. They are made from citrus fruits, melons, cucumbers, even the sweet-tart pulp of tamarind pods. But among the most popular is this one, made by steeping the dried, deep crimson calyxes of the hibiscus flower. This slightly tart, garnet-colored beverage is incredibly beautiful and refreshing. Piloncillo, the unrefined brown sugar used in traditional rustic desserts, adds a mellow, molasses-like sweetness.

This traditional agua gets its glorious red color from the jamaica, or hibiscus, flower, whose natural sourness is counteracted by the sugar.
